Mantle
A Bybit-affiliated Ethereum L2 that transitioned to a full ZK Validity Rollup in 2026.
Mantle is an Ethereum L2 built on the OP Stack that became the first OP Stack chain to migrate to a ZK Validity Rollup, using Succinct's SP1 zkVM. It shifted from EigenDA-backed Validium to full Ethereum blob DA after Fusaka. Backed by Bybit and a large community treasury (over $2B+), it positions itself as an institutional distribution layer with products like mETH, fBTC, and MI4.
- TVL crossed $1B in mid-2026 per Mantle's H1 2026 report, growing rapidly after Aave V3's Feb 2026 launch pulled in $1B in 19 days per Nansen Q1 2026 data.
- First OP Stack chain to launch as a ZK Validity Rollup, using Succinct's SP1 zkVM.
- Migrated to Ethereum blobs as primary DA layer post-Fusaka in 2026, moving from Validium to full rollup security.
- Ecosystem anchored by mETH (LST), fBTC (Bitcoin-pegged asset), and MI4 (index product); native token MNT.
- Community treasury above $2B+ funds ecosystem incentives and RWA initiatives, including tokenized equities and USDe/USDY integrations.
Frequently asked questions
Is Mantle a ZK rollup or an optimistic rollup?
Both, at different times. Mantle originally launched as an OP Stack optimistic rollup with EigenDA for data availability (technically a Validium). In 2026 it migrated to a ZK Validity Rollup using Succinct's SP1 zkVM and switched DA to Ethereum blobs after Fusaka, making it a full ZK rollup.
What is mETH?
mETH is Mantle's liquid staking token, backed by ETH staked through Mantle's staking system. It is the primary yield-bearing asset in Mantle's DeFi ecosystem and is widely accepted as collateral on lending markets deployed on the chain.
How is Mantle related to Bybit?
Bybit is one of Mantle's largest backers and a strategic partner. Bybit provides fiat on/off ramps for MNT and Mantle assets and integrates Mantle-native products like mETH into its yield offerings. This gives Mantle a CEX-scale distribution channel that most L2s lack.
